Wherein X, Y, Z, T, R1a and R1b are as defined in claim 1.
The novel title compounds 6 and 7 were conveniently synthesized by a facile two-step route starting from (2-chloro-2-nitroethenyl)benzenes 2 via the base-induced cyclopropanations of the intermediate 2-(2-chloro-2-nitro-1-phenylethyl)cyclohexanones 3 and 4.
Enantioselective construction of small molecules displaying a configurationally stable helical shape built on a fused-tetracyclic core is a daunting synthetic challenge even more pronounced when five-membered rings are incorporated in the structure. The resulting higher configurational lability strongly hampers their access, and therefore the development of new efficient methodologies is timely and
